<"php://input"); //读取POST过来的输入流
$data=XML_unserialize($xml);
echo '<pre>';
print_r($data);
echo '</pre>';
"htmlcode">

<"1.0" encoding="GBK""htmlcode">

Array
(
 [video] => Array
  (
   [upload] => Array
    (
     [videoid] => 998
     [name] => 回忆未来
     [memo] => def
     [up_userid] => 11317

)




2、将数组转换成XML文件：


<"htmlcode">

<"1.0" "\n"; }
 while(list($key, $value) = each($data))
  if(!strpos($key, ' attr')) #if it's not an attribute
   #we don't treat attributes by themselves, so for an emptyempty element
   # that has attributes you still need to set the element to NULL
   if(is_array($value) and array_key_exists(0, $value)){
    XML_serialize($value, $level, $key);
   }else{
    $tag = $prior_key "\t", $level),'<',$tag;
    if(array_key_exists("$key attr", $data)){ #if there's an attribute for this element
     while(list($attr_name, $attr_value) = each($data["$key attr"]))
      echo ' ',$attr_name,'="',htmlspecialchars($attr_value),'"';
     reset($data["$key attr"]);
    }
    if(is_null($value)) echo " />\n";
    elseif(!is_array($value)) echo '>',htmlspecialchars($value),"</$tag>\n";
    else echo ">\n",XML_serialize($value, $level+1),str_repeat("\t", $level),"</$tag>\n";
   }
 reset($data);
 if($level == 0){ $str = &ob_get_contents(); ob_end_clean(); return $str; }
}
